1. High-power magnification: 20x, 40x, 60x and 100x. These levels clearly reveal fine object details to meet high-detail observation needs. 2. Accurate measurement: built-in scales allow precise measurement of object size. Useful for scenarios where accurate measurement of tiny items supports professional judgments and analysis. 3. Dimmable illumination: LED lights with soft, adjustable brightness. Provides good lighting in dim environments, ensures clear observation details, protects eyes, and reduces visual fatigue from insufficient light. 4. High-quality imaging: internally coated optical lenses with distortion-free edges. Produces more realistic and accurate images of observed objects, enhancing the effectiveness and value of the magnifier. Use scenarios: - Jewelry, gemstones, and coin examination to verify details and authenticity. - Electronics and circuit component inspection for tiny defects. - Collectibles, stamps, minerals, and small mechanical parts requiring precise imaging and measurement.
